Your policy changed during this window

What it means

The loaded reports describe N different published policies, so part of this data was collected under rules you have since changed. Reports always describe the policy that was live when the mail was sent.

How to fix it

Compare like with like: analyse the reports from before and after the change separately when judging whether the change worked.

Check your own domain

This page describes the condition. To find out whether your domain has it, run the RUA test or the full checkup, which examines every record at once.

Understand it properly

This page covers one condition. For the whole picture, The DMARC guide, including how reporting works, or start at the Health Library.

Where this comes from

We judge this against RFC 9990 section 3.3. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.

Other RUA conditions

• You are ready to turn enforcement on
• Some of this is forwarded mail, not an attack
• Somebody is sending as you, and it is being delivered
• Unauthenticated mail is getting past your policy
• Your policy stopped forged mail
• Your own mail is failing authentication
